Allen-Bradley 100-C12-400 Three-Phase Contactor

The Allen-Bradley 100-C12-400 Three-Phase Contactor, paired with the 193-EA1EB electronic overload relay, is designed for IEC motor starter circuits that require dependable switching and solid-state overload protection for three‑phase motors. Commonly installed in control panels, conveyors, pumps, and compressors, it is used by maintenance teams and system integrators for repair, retrofit, expansion, or replacement of motor starter components in industrial equipment. The assembly is a 3-pole device rated at 12 A (AC-3) with 1 auxiliary NO contact; coil voltage is application dependent. The 193-EA1EB overload relay provides adjustable electronic protection with a 1.6–5.0 A range and Trip Class 10, with manual reset. Mounting supports DIN Rail or panel mounting, and the terminals are Screw Clamp. Standards include UL Listed, CSA Certified, and IEC 60947 compliance, suitable for industrial operating temperatures. Typical applications span motor starting, switching, and overload protection in packaging machinery, HVAC systems, material handling, and process automation where compact panel integration and reliable protection are required. Cross references include Allen-Bradley 100-C09D10 with 193-KA overload relay, Schneider LC1D09 with LRD overload, and Siemens 3RT2015 with 3RU overload relays.
